Gas connection
Installation must be carried out so that the length of the piping does not
exceed 2 metres when fully extended; make sure that the hoses do not
come into contact with moving parts and that they are not crushed in any
way. The internal diameter of the hose must be 13 mm for all gas types.
Verify that all the following conditions are met:
•
it is possible to inspect the entire length of the hose (max. 2 m);
•
no part of the hose is in contact with hot walls (Warning: Point
A indicated in the figure reaches 100°C);
•
the hose is not under traction or tension and has no tight curves or
twists;
•
the hose is not in contact with sharp objects or sharp corners;
•
if the hose is not perfectly airtight and leaks gas,
do not try to
repair it
: replace it with a new hose;
•
verify that the hose is not beyond its life cycle.
2.4.1
Connection with a flexible steel hose (for all types of gas)
This type of connection can be made on both built-in
and free-standing appliances. Only use standards-
compliant steel hoses no more than 2 metres in
length. Screw the end of the flexible hose
L
onto
threaded ½” external gas connector
B
with the seal
C
positioned between the two (ISO 228-1).
At the end of the installation, check for any leaks
with a soapy solution, never with a flame.
Make
sure that the hose complies with the applicable
standard.
In the case of connection to a GPL cylinder, use a
hose with an adaptor for connection to the pressure
regulator.
Take care that the hose does not get crushed or
damaged.
